Introducing a better way to type on iPhone. Crimson Keyboard is an iPhone exclusive keyboard that adapts to your writing style and provides smart, personal and contextual suggestions. It shows predictions directly above the keys you’re likely to tap next. Just swipe up on a key to complete the word.



“It really is the best iOS keyboard I’ve used.” — The Next Web
“Like the native iOS keyboard, but better.” — AppAdvice
“Predictive typing without that annoying suggestion bar.” — iDownloadBlog
“I absolutely adore Crimson.” — BeautifulPixels
“One of the smartest keyboards so far. (...) We're deeply impressed.” — iCulture



• Beautiful Design
The native design is refined and improved with delightful animations and a clear shift key. Subtle translucency, click sounds and an automatic contextual dark mode make Crimson feel right at home on your iOS device. The Smart Spacebar provides access to punctuation marks at just the right moments. You can even customize Crimson with different tint colors.

• Smart Predictions
Crimson is powered by Adaptxt, an intelligent prediction engine that learns the words you use and predicts words you're likely to write next. You can even use multiple languages simultaneously, and Crimson will automatically switch between them¹. Learning happens locally on your device, without information being transmitted over the internet. Your privacy is important to us.

• Custom Emoji Keyboard
Crimson comes with its own emoji keyboard, which makes switching to and picking emoji lightning fast. Your skin tone selection is automatically applied to all emoji in the keyboard.

• Passive Correction
Forgot a space or made a typo? Instead of unsolicited auto corrections, Crimson suggests corrections above keys. Just like predictions, swipe up corrections displayed in red to insert them. Still prefer auto correction? This can be enabled in the settings.
